Analysis of Wave Response of a Large Floating Structure in Multi-Directional Waves and Verification by Field Measurement

Abstract

This paper presents analysis of wave response of a large floating structure located at Awaji-island in consideration of multi-directional irregular waves. The multi-directional irregular waves have been reproduced from the measurement values of current speed and water pressure obtained from the field-measurement. The horizontal motions as a moored vessel have been measured and compared with the simulated values in frequency domain. The results have shown that the significant values for the horizontal motions by the simulation agree well with the measured values, when the multi-directional irregular waves are considered.
